I have a problem. My wifi is sketchy at best. I'm wondering if anyone is aware of any tool out there that will allow you to use your wifi card to scan the 2.4GHz spectrum and assess/identify what is happening.

On average they are about 3-4m apart. I have a one bedroom apartment so I only travel so far with my laptop.

Constantly, and I mean constantly, my connection is very unpredictable at best. Not all the time, but it happens in spurts up to an hour at a time.

What I want to do is find something that will allow me to analyze the 2.4GHz specturm with my wifi card so I can see what is going on.

Using /proc/net/wireless stats I see that my Rx signal level is between -40dBm and -50 dBm, decent. however my "link quality" fluctuates all over the map. I want to konw why?

Is it a micowave? A cordless phone? Something else that uses the 2.4GHz ISM band? I want to know.

Any ideas?

Edit:

00:52 You might also try changing the channel00:52 ahh, thought of that00:52 I'm on 1...00:52 It seemed to help when i had that problem00:52 and I'm there because when I moved in I scnanned the specturm and found a shitlod of defaults at 6, and then 3 others on 1100:52 nothing on 100:53 I usually scan the area once a week to seee what's out there00:53 now there 2 others on 1, 3 on 11, and the usual boatlods of defaults on 600:53 i can see about 25-30 other AP's fome my apartment00:53 frome00:53 er00:53 from00:54 so I've look at that wuite a bit

You're using Sveasoft; set the channel, to auto then restart your router, if it sees interfearance from another source on startup it'll scan for a new channel with none; it's also good to have "AP Watchdog" enabled, when it "senses" a problem with no clients attached, it'll restart the wireless service.
